I am also very worried about hackers. Everyone should be careful to protect themselves
You do not need to worry about hackers. I think you only need to use some good security so hackers will never have the chance to hack into your account. One of the best security I frequently use is the two-factor authentication
I'm not sure if you are still in the topic, as it's the exchange itself that was been hacked, so far extra security measured should be implemented and it's also the basis if you will going to invest your money and allow exchange to keep it while you are doing business, if the exchange can be trust storing decent capital can grow but if you are not sure better not invest money that you can't afford to lose,as hackers are just around and waiting for the next victim.
